Key Parameters

Substitute Part Grouping Explanation

Substitution of the SP3220ECA-L is determined by strict equivalence across the following critical parameters:

• Protocol: RS232 full-duplex transceiver
• Driver/Receiver Configuration: 1/1
• Receiver Hysteresis: 300 mV
• Data Rate: 120 Kbps
• Supply Voltage Range: 3V ~ 5.5V
• Package Type: 16-SSOP with identical physical dimensions (0.209", 5.30mm Width)
• Mounting Type: Surface Mount

The substitute part SP3220EEA-L/TR maintains identical electrical specifications and mechanical compatibility with the original SP3220ECA-L, differing only in product status (Active vs. Obsolete) and operating temperature range extension.

Parameter Comparison

Engineering Selection Recommendations

The SP3220EEA-L/TR is a direct functional equivalent to the SP3220ECA-L. Selection of the substitute part is supported by:

• Identical electrical specifications across all critical transceiver parameters
• Identical package and pinout configuration ensuring mechanical compatibility
• Active product status ensuring ongoing availability and supply chain support
• RoHS Compliance and REACH Unaffected status, meeting current regulatory requirements
• Extended operating temperature range (-40°C ~ 85°C) providing broader environmental tolerance compared to the original part's 0°C ~ 70°C specification

For applications requiring the original operating temperature range of 0°C ~ 70°C, the SP3220EEA-L/TR remains fully compatible and suitable for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can SP3220EEA-L/TR be used as a direct replacement for SP3220ECA-L?

A: Yes. Both parts are manufactured by MaxLinear, Inc., share identical RS232 transceiver specifications (1/1 driver/receiver configuration, 300 mV hysteresis, 120 Kbps data rate), operate at the same supply voltage range (3V ~ 5.5V), and are packaged in the 16-SSOP form factor with identical pinout and physical dimensions.

Q: What is the primary difference between these two parts?

A: The SP3220ECA-L is obsolete with a limited operating temperature range of 0°C ~ 70°C, while the SP3220EEA-L/TR is an active product with an extended operating temperature range of -40°C ~ 85°C. The substitute part also carries RoHS Compliance and REACH Unaffected certifications.

Q: Are there any package or pinout differences?

A: No. Both parts use the 16-SSOP package with identical physical dimensions (0.209", 5.30mm Width) and are surface mount components. Pinout and mechanical compatibility are fully maintained.

Q: Does the extended temperature range of SP3220EEA-L/TR affect compatibility?

A: No. The extended temperature range of the substitute part (-40°C ~ 85°C) encompasses the original part's operating range (0°C ~ 70°C). Applications designed for the original temperature specification will operate within the substitute part's qualified range.

Q: What certifications does the substitute part carry?

A: The SP3220EEA-L/TR is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic components.
